RHODE ISLAND, .AssIoNoR To] RHODE ISLAND COLLAR Application filed April 5,

The present invention relates to collar buttons, and has for its particular reference to the formation of a collar button which may be comfortably worn by theuser.

One object of the invention is to provide a collar button base with a concave bottom face portion and a flat supporting edge portion therefor, whereby the bottom surface conforms to the contour of the neck and the flat supporting edge affords a firm support and eliminates any projections tending to induce wear and tear of the wearers shirt.

Another object is to strengthen the supporting edge of the base of a collar button of this type by forming a reinforcing bead thereon. p

A further object is to provide a collar button base which is substantially square in shape, with a flat peripheral edge, and a concave interior depression having a generally circular boundary.

With these and other objects and advantageous features in view, the invention consists of a novel arrangement of parts more fully disclosed in the detailed description following, in conjunction with the accompanying drawings, and more particularly se forth in the appended claims. a

In the drawings:

Fig. 1 is a side elevation of the improved collar button, partly broken away at the base;

Fig. 2 is a top plan view; and

Fig.- 3 is a bottom plan view.

It has been found desirable to provide a collar button which will not roll when dropped on the floor or other horizontal surface, and which has a rigid edge on the base thereof, the bottom face of the base being formed with a flat peripheral portion and a concave inner portion. I have therefore devised a collar button with a generally square base, the bottom face-of the base having a concave inner portion bounded by a circular stepor recess, and a peripheral flat portion,

the edges of the base being rolled over to ensure rigidity against bending or di'stortion and tosimplify the manufacture of the imroved collar button; and the following is a detailed description of a preferred construc- Burrow 1a3o. Serial No. 441,913.

tion embodying the principles of my invention.": p I V j Referring to the drawings, the collar button includes a shank 10 having a head 11 at one end thereof'and a base 12' at the opposite end thereof, said head, shankfand base being-co-axially aligned.- The'base'12 is substantiallysquare, the sides 13 thereofbeing'slightly outwardly curved, and'th e corners 14 being nicely rounded, thus eliininating all sharp edges; the substantially square formation of the baseprevents rolling of the collar button when dropped-on a horizontal surface, such as the floor, a table, ora dresser Pl- Q 1 I The'bottom face 15 of the base has an outer flat peripheral ortion 16 and an innor concave portion 1 the concave portion being preferably circular and preferably countersunk, thus presenting a. distinct circular edge 18 for the concave portion. The

edge 19. of the flat peripheral portion, which includes the sides 13 and'the corners 14, is rolled or beaded, as at 20, to strengthen the edge and to prevent bending or distortion thereof. This construction provides a flat bearing surface for the bottom. face of the collar button, with extended flat bearing surfaces at the corners of the bottom face.

The concave inner portion is shaped to conform to the neck of the wearer, while the flat peripheral portion eliminates all projecting corners or edges, thus'providin'g a more comfortable contact of the base with the neck of the wearer, and eliminating wear and tear on the neckband, in the case of a back button, through use of the fiat bearing surface and the extended corner bearing surfaces. The rolled over edge strengthens the base'and permits use of thinner material, while at the same time adding to the attractiveappearance of the collar button and facilitating the manufacture thereof.

While the specific embodiment described and illustrated has a base of generally square outllne, changes in outline by using other polygonal'base shapes, or changes in the relative extent of the concave and the peripheral the like, may obviously be made, Within the spirit and the scope of the invention as defined in the appended claims.

I claim:

1. A collar button comprising a shank, a head at one end thereof, and a polygonal base at the other end thereof, the bottom face of said base having a flat peripheral portion and a central concave portion.

2. A collar button comprising a shank, a head at one end thereof, and a polygonal base at the other end thereof, said base having a bottom face including a flat peripheral portion and a central concave portion, and

a rolled edge extending completely about the periphery thereof.

3. A collar button comprising a shank, a head at one end thereof, and a generally polygonal base at the other end thereof, the bottom face of said base having a flat peripheral portion and a central circular concave portion, whereby a flat bearing surface enlarged at the corners is provided.

4. A collar button comprising a shank, a head at one end thereof, and a base at the other end thereof, the bottom face of said base having a fiat peripheral portion and a central circular concave portion countersunk in said flat peripheral portion.

In testimony whereof I aflix my signature.
